220 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 9 



Dorsal VII — 11 (12 in one paratype), origin slightly behind vertical 

 through base of ventral fin. Dorsal spines flexible, moderate. First spine 

 shorter than second, third spine reaching to origin of second dorsal when 

 depressed. Predorsal length 2.6 to 2.84 in standard length, (35.2 to 

 37.7% of standard length). Soft dorsal moderate, rays not reaching 

 beyond caudal base when depressed. Anal fin 10 (11 in one paratype), 

 origin under second dorsal ray. Pectoral 17 or 18, longest ray barely 

 reaching origin of second dorsal, 3.46 to 4.9 in standard length (26 to 

 29.8%). Ventrals completely united, free from abdomen; interspinal 

 membrane well developed, 4.5 to 4.7 in standard length (22.2 to 

 24.8%). Posterior edge of disk not reaching vent by length of inter- 

 dorsal space. 



Body entirely naked, no scales at base of caudal fin. Head moderate, 

 3.38 to 4.1 in standard length (28.4 to 29.6%). Head width greater 

 than depth immediately behind orbit, 5.4 to 5.9 in standard length (16.8 

 to 19.1 %o). Head depth 6.9 to 7 in standard length (14.3 to 14.5%). 

 Dorsal and ventral outlines of head bluntly rounded to vertical through 

 eye, thence extending backward almost horizontally to posterior edge of 

 head. Snout short, blunt, 4.49 to 4.74 in head (6 to 6.6% of standard 

 length). Eye m.oderate, 3.5 to 3.9 in head (7.6 to 8.4% of standard 

 length). Mouth terminal, oblique, lower jaw slightly included at tip. 

 End of maxillary reaching or almost reaching a vertical from center of 

 eye, 2.3 to 2.48 in head (11.9 to 12.6% of standard length). 



Teeth in jaws in villiform bands; wide anteriorly, becoming narrow 

 laterally. Outer row of teeth in each jaw enlarged. Tongue broadly 

 emarginate. Nostrils paired, tubular. Tube of anterior nostril conical, 

 opening small, porelike. Tube of posterior nostril cylindrical. A small 

 but distinct barbule present on inner edge of upper jaw below anterior 

 nostrils. A small barbule also present below eye at a vertical through 

 anterior edge of pupil, and just anterior to the first vertical row of 

 cutaneous papillae. Mental frenum bilobed, the lobes widely separated 

 and barbel-like. 



Head with longitudinal and transverse rows of cutaneous papillae. 

 Two rows ventrally on underside of lower jaw, continued posteriorly 

 upward around edge of preopercle and ending in an enlarged pore at the 

 level of the lower edge of the eye. On either side of the dorsal mid-line of 

 the snout two short rows of papillae extend backward from the inner 

 edge of the upper lip, between the anterior nostrils, and unite with an
